Abstract

A selvage yarn shedding apparatus of a loom including two support bodies each having carrier rods configured to support a heddle into which a selvage yarn is inserted and a slide guide having both end portions to which the carrier rods are attached; a drive motor configured to drive in forward-reverse rotations; a support frame including a guide member; and a motion conversion mechanism configured to convert rotation of an output shaft of a drive motor into reciprocating motion in upper-lower direction of each support body. Each of the support bodies includes a connecting part including an extension portion provided above the carrier rod and extending from the slide guide in a longitudinal direction of the carrier rod toward a side where the heddle exists, where the connecting part is configured to connect the slide guide and the motion conversion mechanism each other at the extension portion.

First claim

The invention claimed is:

1. A selvage yarn shedding apparatus of a loom comprising: two support bodies each having carrier rods configured to support a heddle into which a selvage yarn is inserted and a slide guide having both end portions to which the carrier rods are attached; a drive motor configured to drive in forward and reverse rotations; a support frame fixed to a loom frame and comprising a guide part configured to guide displacement of the slide guides in an upper and lower direction, the drive motor being attached to the support frame; and a motion conversion mechanism configured to connect an output shaft of the drive motor and both the support bodies each other and to convert rotation of the output shaft into reciprocating motion in the upper and lower direction of each support body,
wherein each of the support bodies comprises a connecting part including an extension portion provided above the carrier rod and extending from the slide guide in a longitudinal direction of the carrier rod toward a side where the heddle exists, where the connecting part is configured to connect the slide guide and the motion conversion mechanism each other at the extension portion.

2. The selvage yarn shedding apparatus of a loom according to claim 1 , wherein each connecting part is connected to the motion conversion mechanism within an existence range of the heddle in the longitudinal direction.

3. The selvage yarn shedding apparatus of a loom according to claim 1 , characterized in that each connecting part is formed as a separate body from the slide guide and is detachably attached to the slide guide.

4. The selvage yarn shedding apparatus of a loom according to claim 2 , characterized in that each connecting part is formed as a separate body from the slide guide and is detachably attached to the slide guide.
